Teams will use an aero package that will be similar to what Xfinity used in 2017 at Indianapolis. Larger front splitter, Front Aero Ducts, 6 Inch Spoiler with and additional 6 Inch ‘Rabbit Ears’ attached to each end.

*Team charter agreements forbid NASCAR to make any significant aero changes during the season. One reason you won’t see this package in the Cup series this year except for this race.
